Every year starting April 16th, there is a ban on fishing in the Tamilnadu Coast from Thiruvallur to Kanyakumari Districts. Since scientists found fish breeding to be active in the eastern coastal belt during April and May, fishing by mechanised boats from Thiruvallur to Kanyakumari districts is prohibited between April 15 and May 29. The ban excludes fishing by country boats and catamarans.
